Mac OS X only: Free Mail.app plug-in WideMail adds a new three-paned display and customization options to OS X's default email client. Similar to previously mentioned Letterbox, WideMail offers more advanced settings for tweaking how Mail.app displays and formats your email. If you've got a widescreen monitor and you prefer the way the three vertical pane interface lays out your email, WideMail is just the ticket. Thanks Jason!
